Questions
How big is the IndegoMower PCB?
It measures 172 × 230 mm and has 2 copper layers, 1.58 mm thick.
What parts does the IndegoMower use?
34 parts, built around the L298P, 26SHC-B-1A, P4SMAJ5.0CA and BNO055. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the IndegoMower KiCad files?
From the MS71/IndegoRover repository on GitHub, at the commit this page was made from: the board is kicad/MainPCB/IndegoMower.kicad_pcb and its schematic kicad/MainPCB/IndegoMower.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IndegoMower design in my own project?
Its repository states no licence, so its author keeps all rights: ask MS71 before reusing the design.
